To assess the predictive value of carotid bruit for moderate-to-severe carotid atherosclerosis, the results of carotid arteriograms performed on 1004 subjects were correlated with the findings of auscultation of the carotid arteries. Predictive values of carotid bruit for ipsilateral extracranial carotid atherosclerosis were 77% for localized bruits and 74% for diffuse bruits. The predictive values of extracranial carotid bruit for ipsilateral intracranial carotid atherosclerosis were 16% for localized bruits and 18% for diffuse bruits. Assessing both carotid arteries together, the predictive value of carotid bruit for moderate-to-severe atherosclerosis at any extracranial carotid site was 85%, there being no difference whether the bruits were diffuse, localized, bilateral, or unilateral. Diffuse or localized bruits, whether unilateral or bilateral, are equally predictive of moderate-to-severe atherosclerosis in the extracranial carotid artery, but both are poor predictors of intracranial carotid artery disease.
为评估颈动脉杂音对中度至重度颈动脉粥样硬化的预测价值，对1004名受试者进行的颈动脉血管造影结果与颈动脉听诊结果进行了相关性分析。局限性杂音对同侧颅外颈动脉粥样硬化的预测价值为77%，弥漫性杂音为74%。颅外颈动脉杂音对同侧颅内颈动脉粥样硬化的预测价值，局限性杂音为16%，弥漫性杂音为18%。综合评估双侧颈动脉时，颈动脉杂音对任何颅外颈动脉部位中度至重度粥样硬化的预测价值为85%，无论杂音是弥漫性、局限性、双侧性还是单侧性，均无差异。弥漫性或局限性杂音，无论单侧或双侧，对颅外颈动脉中度至重度粥样硬化具有同等的预测价值，但两者对颅内颈动脉疾病的预测价值均较低。
